Cold floors and high heating bills often start in the basement. We insulate and air seal Kokomo basements so your home holds heat the way it should.
Cold floors and high heating bills often start in the basement. We insulate and air seal Kokomo basements so your home holds heat the way it should.

Basement insulation in Kokomo creates a thermal barrier between the cold ground and your living areas - most jobs take one to two days and include insulating the walls or ceiling along with sealing the rim joist where cold air enters most aggressively. When that barrier is missing or thin, your furnace fights an uphill battle every winter and your first-floor floors never quite feel warm.
Most Kokomo homes built before 1980 have little to no basement insulation. The good news is that this is one of the most cost-effective improvements you can make to an older home - because you are stopping heat loss at the source rather than trying to compensate for it with a bigger furnace or higher thermostat. Basement insulation works closely with crawl space insulation when a home has both types of below-grade spaces, since heat loss patterns in the two areas are often connected.

If your kitchen or living room floors feel cold even when the heat is running, the basement below is likely uninsulated or under-insulated. In Kokomo's winters - where temperatures can stay below freezing for days at a time - heat from your living space escapes straight down into the unheated basement. Better insulation at the basement ceiling or walls stops that loss and makes the floors noticeably warmer within the first heating season.
If your gas bill climbs sharply from October through March and your thermostat never seems to keep up, your basement is likely one of the biggest culprits. In Kokomo's climate, an uninsulated basement can account for a significant share of your home's heat loss each winter. If you have noticed this pattern for more than one winter, it is worth having a contractor inspect the basement.
The rim joist - the framing where your floor meets the top of the foundation wall - is one of the most common places for cold air to enter an older home. Look up near the basement ceiling on a cold day. If you can see daylight, feel a draft, or notice bare wood sitting directly on concrete with no insulation in between, that area is a significant source of heat loss. This is especially common in Kokomo homes built before 1980.
Moisture and insulation problems often travel together. If your basement walls sweat in humid summer months, if you notice a persistent damp smell, or if you see white chalky deposits on the concrete, the thermal balance in the space is off. Indiana's clay soils and humid summers push moisture into unprotected basements. Addressing insulation and air sealing together helps stabilize temperature and reduce the moisture problem at the same time.
Every basement insulation job starts with an assessment. We look at the walls, ceiling, and rim joist area, check for moisture or cracks, and identify what is already there and what needs to change. Before insulation goes in, we seal gaps, cracks, and penetrations in the rim joist and foundation framing - because insulation without air sealing is like putting a sweater on over a shirt full of holes. For homeowners who want the full picture on spray foam as a basement option, we also offer closed-cell foam insulation as a dedicated service that combines insulation and air sealing in a single application.
After the air sealing is complete, we install the appropriate insulation material for your basement type, budget, and goals. For finished or soon-to-be-finished basements, we typically work along the perimeter walls. For unfinished basements, ceiling insulation above the basement floor is often the right call. Either way, the work is done cleanly, the crew walks you through the finished job before they leave, and the price is written down before we start. Homeowners looking for comprehensive protection below and around the foundation may also want to consider crawl space insulation as a companion project.
Best for finished or soon-to-be-finished basements where the walls are the primary surface to protect.
Best for unfinished basements that will stay unconditioned, focusing on warming the floor above.

Kokomo sits in north-central Indiana, where average January lows regularly drop into the single digits and the heating season runs nearly six months. That kind of sustained cold puts enormous pressure on an under-insulated basement. A large share of Kokomo homes were built between the 1940s and 1970s, when basement insulation was rarely included and building techniques left gaps throughout the foundation framing. In these homes, the rim joist area is often completely bare, and cold air moves freely into the living space above. Getting the basement right here pays back faster than it would in a milder climate - because the temperature difference between outside and your floor is so large for so many months. Homeowners in Anderson deal with the same cold-season conditions and see similar results.
Indiana's freeze-thaw cycles are another factor that matters here. Kokomo goes above and below freezing many times each winter, which opens small cracks in poured concrete and block foundation walls over time. A contractor who checks for those cracks before insulating - rather than covering them up - is doing the job right. The glacial clay soils throughout Howard County also hold moisture near the surface, which is why moisture assessment is always part of our basement evaluation. Homeowners in Elwood face the same soil conditions and the same risk of moisture working into below-grade spaces if the thermal envelope is not properly closed.
Federal tax credits and utility rebate programs from providers like ENERGY STAR-qualified improvements may offset a meaningful portion of your project cost. The IRS Energy Efficient Home Improvement Credit covers up to 30 percent of qualifying insulation material costs through 2032.
Call or submit a request online and we will get back to you within one business day. We ask a few basic questions - your basement size, whether it is finished or unfinished, and what problem you are trying to solve - so we come prepared to the estimate visit.
We walk through your basement, inspect the walls and ceiling, check for moisture or cracks, and measure the space. We look at what is already there and identify what needs to be done first - no charge for this visit and no pressure to book.
You receive a written estimate that specifies the insulation type, the areas being covered, and whether air sealing is included. If you are comparing quotes, make sure each one covers the same scope - a lower price sometimes means less work is actually being done.
The crew arrives, clears the work area you have prepared, and completes most jobs in one to two days. Before leaving, we walk you through what was installed and where - so you can see the work firsthand and ask any questions before the final invoice.
Free in-home assessment. Written quote before any work starts. No pressure.
(765) 776-9811We inspect for efflorescence, condensation, and cracks before a single inch of insulation is installed. Insulating over a damp wall traps moisture and leads to mold - a mistake that costs far more to fix than the original job. We flag moisture issues during the assessment and explain what needs to happen first.
The rim joist is the most common cold-air entry point in a Kokomo basement, but it is also the most commonly overlooked. We air seal this area as part of every wall insulation job - not as an add-on. A sealed rim joist often delivers more improvement per dollar than any other single change in an older home.
We work regularly in Kokomo homes built before 1960 - brick bungalows near downtown, postwar ranch homes on the south side, and everything in between. Each era of construction has its own quirks, and we know what to look for in each one. That local knowledge means fewer surprises and better results.
Every estimate we give is written and itemized before work begins. You will know the insulation type, the area being covered, and whether air sealing is included - all on paper. The price you agree to is the price you pay. The Building Performance Institute sets the standard for this kind of transparent, whole-home approach.
Every basement job we do in Kokomo starts with an honest assessment and ends with a walkthrough. We want you to see the work and understand what changed - not just take our word for it.
